He said they did some plumbing work on the shop earlier this year. Prior to the second quarter coliform sample. Second quarter coliform sample taken on 6/19/18 and non detect. I sent him the well disinfection document and will be meeting George on site by early next week.

Update 09/25/2018:  System shocked last week and 2 coliform samples taken in distribution on 9/21/18 came back positive for TC. Samples labeled repeats, should have been labeled special. System will be shocked system again and take more special samples.

Update 09/26/2018:  Jeron shocked the well and only used 3/4 cup chlorine. I informed him he would need 2.25 cups 8 chlorine. He also wasnt sure how old the chlorine was. He will purchase new chlorine and use 2.25 cups chlorine and shock the well again tomorrow. He will take a couple special samples early next week.

Update 10/09/2018:  Spoke to George today. They shocked the well again last week. They followed the disinfection guidelines and took two samples in distribution. One sample came back Total Coliform positive. I recommended they contact a professional to come out and shock the system for them. George will let me know when they have that scheduled.

Update 11/07/2018:  Spoke to George. System has been shocked a total of 3 times since they went on a Boil Notice. Theyve taken numerous special samples and none of them have been ecoli positive. Several are total coliform positive and the others are non-detect. I recommended they take another source sample.
